Summary: | A supramolecular approach for modeling active sites of metallo-enzymes relies on the association of a metal ion bound to a tris(imidazole) core under the control of a cavity. One step further is the water-solubilization of the cavity-complex. Here, we describe the synthesis of a water-soluble bowl-ligand that has been successively achieved through an 11-step strategy from resorcinol. First insights into its coordination properties in water show that it readily binds Zn(
ii
) at physiological pH and acts as a molecular receptor for the hydrophilic acetate guest ligand.
The bowl-shaped cavity-ligand based on resorcinarene has been successfully transposed into a water-soluble version that readily binds Zn(
ii
) and acetate at physiological pH. |
